Automatic Rain Gauge
RainVUE™️20
The RainVUE™️20 is a high-precision SDI-12 tipping-bucket rain gauge designed for hydrological and meteorological applications, including weather stations and flood early-warning systems. Using advanced digital processing, the sensor automatically compensates for errors caused by high-intensity rainfall, ensuring accurate precipitation and rain-rate measurements.
Built with an aerodynamic, powder-coated aluminum funnel, the RainVUE™️20 minimizes wind-induced losses and provides long-term durability. Users can choose from standard cable lengths or specify custom lengths for installation flexibility.
